Contactless Bio-Impedance Monitoring Technique for Brain Cryosurgery in a 3D Head Model1

Nanowires network for biomolecular detection using contactless impedance tomoscopy technique.

Here we present the detection of ultralow concentrations of biomolecules in a device made from a polycarbonate membrane containing a network of gold nanowires and using a "contactless" impedance tomoscopy technique. The sensor comprises a thin dielectric layer with two parallel band electrodes on the one side and a microchannel containing gold nanowires onto which the adsorption of antibodies o...

A Contactless Electrochemical Impedance Measurement Method

We present the first demonstration of a passive, contactless method to interrogate electrochemical impedance (EI) via a microfabricated MEMS coil. EI measurement was achieved using the principle of reflected impedance between a pair of inductively coupled coils. Ionic concentration and electrolyte temperature were wirelessly transduced from measurement electrodes connected to a microfabricated ...

Non - invasive Bio - impedance Measurement Using Voltage - Current Pulse Technique

Noninvasive detection is a fundamental prerequisite for pervasive healthcare system and biosensing. Along with different noninvasive techniques such as ultrasound, X-ray, magnetic resonance and optical imaging, electrical impedance spectroscopy is emerging as more suitable technique for tissue level diagnosis. This paper presents a noninvasive technique for bioelectrical impedance estimation by...

Contactless Test Access Mechanism for 3D IC

A Contactless Technique for Measuring Minority-carrier Parameters in Silicon

Characterization of minority-carrier parameters is a primary interest for a range of devices, including solar cells. For “on-line” testing needs, contactless techniques are mandatory, as any diagnostic requiring contact formation is impractical. Here, we will describe the resonancecoupled photoconductive decay (RCPCD) technique that has proven to be a valuable diagnostic for a number of semicon...
